Why are we dependent on Google to enable MTE on the OS-side? If it's a hardware feature, why couldn't GrapheneOS enable it in GrapheneOS even if Google's OS wouldn't enable it?

Because google may have disabled it due to issues/errata. Google willing to enable it is a good sign it is fine, and at worst, affects stock OS as well. Google isnt answering GrapheneOS when they ask why it was disabled, so GrapheneOS cannot know if the implementation is acceptable or not.
